When I made up my mind to go with some new radius arms the other day I did a bunch of reading on the Superior Superflex. The Aussies are reporting great things about them, the only reason I figure I might consider them.
I researched the year before I bought my 80, including countless emails with Superior Engineering, regarding the difficulties I'd known the "lifted" 80 front suspension/driveline to pose, and was sold.
3 link attributes with caster corrective radius arms, all without plates, drops, or the likes.
Sold me.....even after a seasoned pro claimed them "alchemy".
High quality and 5 times heavier than the OE arms, no joke....which comes in handy wheeling Braille, considering how low they hang.
95% there, but not an all inclusive solution.
Sorry I am slightly confused by this portion of your post. Do you have the Superior arms and want to get rid of them and are you warning me what I may have to do to run them?
Yes, possibly, and yes.
They're not the solution I understand you're seeking.
I am just looking to dial in castor and get it driving sweet without using offset bushings, plates or drop brackets.
I don't really need a lot of flex as this truck is not going to be used in the rocks much at all. Just not willing to beat up this nice 80.
So....
I am just not seeing that though when I can bolt in Slee arms.
^^Exactly^^
Based on the descriptive use, my opinion, having ran the SE arms for nearly two years, is Slee's are the better solution in your case.
By the way, I am already part time 4wd.
That was half the battle I fought, being AWD with complex pinion angles.
Even yet, the caster issue remains.
Cliffs
But SE arms suitable for 4-5" lift.
Buy 4" flexy coils that netted 5".
Caster issues abound.
Ratchet strap it to the rack to lower to 4" and check, still not even close to spec.
Couple steering issues with 37" Krawlers and it can be an interesting drive.
Frames been checked, axle verified straight, and the only solution I can see is to cut and turn.
